PIPE LIFTING OR LOWERING MACHINE. l

SPECIFICATION forming part of Letters Patent No. 627,007, dated June 13,1899.

Application filed August 3, 1898.

To all whom, t may concern.'

Be it known that I, L D MOUSER, a citizen of the United States, residingat Imperial, in the county of Chase and State of Nebraska,

have invented new and useful Improvements in Pipe Lifting or LoweringMachines, of

which the following is a speciiication.

My invention relates to improvements in pipe lifting and loweringmachines, and per- 1o tains to a machine adapted to either lift or lowera pipe or rod through the medium`of a lever, all of which will be fullydescribed hereinafter and particularly referred to in the claims.

The object of my invention is to provide a simple and effective machinefor raising and lowering pipes in Artesian and other wells, though itmay be used for handling rods equally as well.

In the accompanying drawings, Figurel is a perspective view of a machineembodying my invention. Fig. 2 is a detached view of the lower dog. Fig.3 is a longitudinal seotional view through the lower dog.

The invention is especially adapted for lifting a pump, detaching itfrom the stock, and then raising or lowering the tube or stock of thepump, as well as for handling rods and metal tubes in connection withArtesian wells.

Referring now to the drawings, A indicates the base-sills, which areunited at their rear ends through the medium of a cross-piece B.Projecting from these sills Aare the vertical standards B', and betweenthe lower ends of 3 5 these vertical standards is a block D, a securing-bolt E passing through the sills, the lower ends of the standards, andthe block D, thus uniting them all together. Resting upon the tops ofthe ends of these sills, projecting be- 4o yond the standards B', arethe blocks F and G. Formed in the upper faces of these blocks andintermediate their ends are sockets H, which are adapted to receive thepivotal points I of the lower dog J. This lower dog consists of a bar K,which carries the said pivotal points I, and secured to this bar K andextending parallel to each other are the plates L, of which there aretwo at each side. Secured between these plates L,near their upper endsand adjacent the bar K, is a plate M, which isv secured between theplates L. The

pivoted between the plates L and its otherV side held in position bymeans of the set-screw Q, which passes through the upper plate L,through the plate P, and screws into the lower plate L. The plates L atone side are provided with a plurality of pivotal openin gs R, wherebythe plate P may be adjusted back and forth to bring it nearer to orfarther from the plate or jaw M. These plates M and P, in fact, formjaws, the upper edge of the lower one, P, being curved, as shown at S,the edge of the curve being tapered at the top and also at its lowerside, as illustrated. By means of the adjustment of this plate the lowerdog is adapted to be adjusted to pipes or rods of different sizes, aswill be readily understood.

The block F upon the top of one of the sills Ais pivoted at its rear endat the point T and is held at its opposite end by means of a verticalpin U. The objectin having this block to swing to one side is to enablethe lower dog to be detached and used to clamp the head of the pump thatis being removed for unscrewing it from the stock.

The pivotal points I of the lower dog are held in their sockets againstvertical movement through the medium of the bands a, which are curvedupward at their centers to pass over the said pivotal points I andbolted at their ends to the blocks F and G, respectively.

.Iournaled to the side of one of the sills A is a rock-shaft h, which isprovided at its rear end with a U-shaped crank c, forming afootpiece, bymeans of which the rock-shaft may be oscillated, for a purpose to bespecified hereinafter. The opposite and forward end of the rock-shaft isprovided with a crankarm CZ, and attached to this crank-arm d is a hookc, adapted to catch in an eye f, carried by the outer end of the lowerdog J.

Projectingupward from the blocks F and G are standards g, attached tothe said blocks in any desired manner and connected at their upper endsby cross-bar h. These bars are IOO connected with the standards Bthrough the medium of the braces 't'. The cross-bar h is provided with ahook 7:., adapted to cooperate with the upper dog in a manner which willbe hereinafter set forth.

The upper ends of the standards B areV 1 the said lever, and thisstraight portion p of the hook is provided with a projection q.`

This projection is adapted to enter the spout of a pump for the purposeof lifting the pump up, as will be readily understood.

The upper dog consists of two levers 2, which are bulged outward, asshown at 3, for the reception of the stock of the pump or a tube or rod,and their outer ends diverge, as shown at 4, and are connected throughthe medium of an adjustable bolt 5. This bolt has one end screw-threadedand adapted to pass into the end 4E of one of the levers 2, and itsopposite end is fiat and passes between jaws 6 of the other lever and isheld in position by means of a set-screw 7. Through the medium of thisconstruction the removal of the setscrew 7 will enable the bolt to beturned and the levers to thus be adjusted as may be desired. Theopposite ends of these levers are provided with openings 8, into andthrough which the lower ends of the links 9 pass. The outer sides ofthese links 9 are provided with the offsets lO, and passing around theselinks is a ring Il. The ends of 'the ring Il are preferably made squareor straight to lit the corresponding edges of the links l0, and theupperends of these links are provided with openings 12, through which aring let passes, said ring adapted to receive the hook n beforementioned. Passing through one of these levers 2 and abutting againstthe other is a set-screw 16, byaneans of which the levers may be forcedapart for the purpose of releasing a tube and by means of which thelevers can also be prevented from closing so tightly upon a tube as toinjure it. In operation when the upper dog has been placed around thetube to be raised the ring ll will fall sufficiently upon the links tohold them clamped against the tube, and yet by the lifting of the ringthe levers 2 can be caused to release the tube.

Braces l5 have their upper ends connected with the standards I3 andtheir lower ends united with the sills A, the bolts which unite thesebraces to the sills passing through a nut at the lower side and arepointed, as illustrated in dotted lines, for the purpose of entering theplatform and preventing the lifting-machine from slipping.

In operation the projection p of the lever m is placed in the spout ofthe pump (when a pump is to be raised) and the pump lifted.

The short end of this lever The upper dog is then placed in positionaround the top of the pump and the stock also passed through the lowerdog J. The downward pressure upon the long end of the lever m will liftthe stock, and when released the stock is caught and held by the lowerdog J, all of which is well understood by those skilled in the art. y

When it is desired to lower a tube in position, the bolt 5 is hookedover the hook 7c of the bar h, and by a downward pressure upon theleverm the upper dog will be slightly raised,which will release it to thedegree it is lifted by the lever m, thus permitting the tube to drop ashort distance, and this dropping of the tube is also effected throughthe inedium of the rock-shaft h and by the foot of the operator upon theU -shaped crank c, which will either lift or depress the lower dog J, aswill be readily understood. These parts last mentioned are only broughtinto operation when it is desired to lower a tube into position.

I-Iaving thus described myinvention, what I claim, and desire to secureby Letters Patent, isj l. A pipe lifting and lowering device cdmprisingan elongated base provided at one end with standards, a lifting-leverfulcrumed between said standards, a lifting-dog attached to the shortend of said lever, a holding-dog pivotal] y supported in the base underthe lifting-dog, and a rock-shaft journaled to one of the longitudinalbeams of the base and eX- tending its entire length and having at oneend a'transversely-rocking crank, connected IOO to the free end of theholding-dog by a link and the otherend provided with an operatingcrankbelow the handle end of the lever, whereby the operator can operate boththe crank and the lever by his foot and hand at the same time,substantially as described.

' 2. Ina machine of the character described, a lifting-dog consisting oftwo levers one car.- rying a bolt, the free end of which is adjustablyconnected to the other lever, said levers being shaped to receive apipe, links attached to the other ends of the levers and havingshoulders a ring ad justably supported thereon and an eye connecting thefree ends of the links and adapted to be attached to a liftinglever,substantially as described.

la base, standards projecting therefrom, a lever fulcrumed upon thestandards, a holdingdog carried by the base, a lifting-dog attached tothe lever, said lifting-dog comprising two IIO levers pivotally and adjustably connected at one end, links connecting their opposite ends, theopposite ends of the links adapted to be connected with the said lever,a ring coacting with the links, the links provided with shouldersadapted to support the ring at different points, substantially asdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
